Referring re ehe drawings, the reference numeral l designates e drum or easing which forms the mixing chamber. The drum may oe suppored in any suitable manner, es h v brackets 2, arranged on supports er foundations Ii desired7 the outer mili 4 may be arranged around the drum forming a nesting or cooling space Heeeing;r or fooling liquids may be passed into' this space iirough inet 6, and exhausted through Outlet The drum is provided 'with an iniet 8 for the solution to be treated and with an opening severed by e man hole @over E), for the admission of carbon 0r other materiel for treating the soiution, reveiving si'ie i0 is arranged in the center of' rire drum, the shaft being mounted in snitebie bearings 1l et each end. `This shaft is provided wih Diaries 12, andthe drum is provided with simiier aiternately disposed piaes 13` `for agiteting and mixing the car- "oon or other .materiel with the solution.

The shaft l() is driven from e suitble sonrce of power by `ineens of e; beit le, passing over e puiiey 15, arranged on a, shaft i6, supported in suitable bearings 17 and 18. The bearing 18 is carried by the shaft 10, es shown. A pinion i9, on the shaft 16 meshes with a gear 20, on stuo shalt 2l. The stub shaft is mounted in suitable henrings 22. arranged on the frame ot the inaehine, and this shaft is provided with a pinion 23. meshing with e gear 24e, carried by the huh of the shaft 10. It will he apparent. that the sin-itt l() is revolved at n less speed than the shaft 16.

The filtering chamber 25 is arranged edjecent the mixing chamber or drinn. and is in communication therewith. the end of the drum being open. A plurality of iltering elements are arranged within the tiltering ehiiinber. each of the iltering elements being slightly vless than half the size of the, filtering chamber wherebyv n central longitudinal opening 27 is provided for the pas sage of' tne material being treated (see Figure 3). As stated, the filteringelements are spaced from each other, to provide intervening spaces 28 into which the solution flows from the longitudinal space 27.

Each of the filtering elements comprises a trame having end members 29 and 30, one of which is curved to conform. to the ontline of the filtering eliznnher. Suitable spacing mernhers 31 are arranged between the end members. and these inenihers are providwl with recesses 32 to permit 'How of the solution Within the filteringr chambers. perforated plzite 83 is arranged on each side ol the filtering traine. Aand this pluto provided with a covering 34, ot' wire mesh. or other suitable material. An outer roverin, r 35 of filtering rloth is arranged over the wire mesh. rl`he wire mesh :and the perforated plate are secured to the trame in any suitable manner. The onter Coveringol filter cloth extends entirelyv around the traine (ser Figure. 7) and is sernred thereto h v ineens of n Wire 36 p sin@` tliron'lgh oi'ienings 3T in the end Walls ol Ilie frame. i

The ilteriner frzunes :ire eznfh provided .i'ith-onil-ri openings PS romnninirnling with firnin pipes.

'Sniziiile parle ing glands l2 nnly lie arranged nroninl the outlet gripes. Its shown, the outlets il? ot' the filtering irzinies are provided with 'suhsnninlljv spherical sorltets 423. for the rrception ol' the ends of the drain pipes ivhirh :ire rnxreil to tit the sockets. The lillerino; freine. is supported Within the iltering)r clieinher 'by ineens of bolts ll. arranged hetieen the lower `mills of the frame and adapted to be received by nuts e6, arranged in recesses 471 ot enlargements 4S. :tornied on the drain pipes. Suitable, lugs or projections 4.9 on the brise of the tllteringr Chamber serve to retain the drain pipes .in proper position, and the trznnes are retained in posit-ion by tightening the bolts atei, The

slot-s (notI shown) in the side wells.

weones inner fece oi? the nut el@ is rounded, Wherehy slight adjustment of the end of the drain pipe may be secured to insure proper'tit. within the socket it. The top of the filtering frames ere held in place by rneinoers 50, similar in construction to the drain pipesj ont provided with closure oeps 5l.

illithin the filtering chamber, there is provided e plurality of Scrapers or buckets :32, secured to the shaft l0, and extending ont werdly to s' point near the Well of the chamber. @ne of these buckets is arranged in each of the spaces 28, and the side walls ot' the bucket are adapted to remove earloon and other solid matter from the faces of the filtering frame. The buckets are provided with bottoms 54, and as the buckets revolve, the carbon or other solid material collected, is delivered to the interior of the shaft l0 through openings 55. The shaft may he provided with a pliirelity of eross plates 5S dividing the space into s plurality of chambers 57 corresponding in number to the buckets 52. it the other end of' the shaft, a. worin conveyor 58 is arranged on the shett 16 within the hollow shaft l0. The end of the shaft l0 is provided with n eirenler plete yand a curved plate 60, spec/ed therefrom providing a. chamber 6l. A illuralitv of radial 'Diaries 62 are arranged within this space supported on :i hub 63 keyed to the shaft 16. The chamber 6l is provided with a, circumferential outlet 6st.

The side Walls G5 of the filtering rheinliers may he hinged to the top, as at G6, und secured in position by means ot hinged bolts 6?.' n'rrangedstthe. top and bot-tom of the filteringF chamber and received in The holt-s are pn'ivided with nuts titi, to .retain the side Walls in position.

The desired ln'nonnt of rurbon, or other nniterinl is tirst shined in the drinn by removing the man hole l). Alter the earlion has heen placed in the drum, and the Cover replaced, the shaft 1G is revolved at n slow rate ot speed and the. carbon or other material is thoroughly ndinixed in the solution by ineens of the blades l2 and 1Q. From the mixing drum, the materiel being treated flows intothe filtering chamber and passes to the spaces 28 between the filtering frames through the longitudinal space QT. llroni the longitudinal spaces the liquid passes into tie iltering trames, the oerhon and other solid impurities being deposited on the riltering `cloth. The deeolorized and Leeeyoee ieroln ion of the elicit l() causes the Ill@ g; iremos, the carbon :ind other coilectcd Lceasing into the through openings This mate etnrned to the mixing drone by the Worn? conveyor 58 and is deliver-ed ont- Wardly by the redini blades 62, through ontlet opening' 512. The provision of the radial blade '62 ists in thorough interinintnre of tiie returned carbon with tne solution in the inixino' chamber. 'The elicit l5, Worm conveyor o8, end radial blades t@ nre revolved at e relatively nigh rate of speed 'to insure return oi" the carbon. from the inicii'eis 52 to the mining chamber.
